Having both programs run at 5 minutes intervall, I create automatic versioning (999+ versions). I can simply go back in time and check exactly when something was done improperly, or to return to previous ideas that have been deleted.

Just to add to this: I've been using an app called ForeverSave2, which can be configured per app to save individual versions at a given time interval, kept for so many days.
It's saved my bacon a couple of times, where I had the "magic disappearing lyrics" bug, and not noticed, and then continued adding to the document. I was able to dig out a version from two hours previously, and copy over the lyrics while keeping my new work.
